Refer to LCD L34975 for the detailed reasonable and necessary clinical criteria and documentation required to support coverage of NEPs.
Use CPT codes 95925, 95926, 95927, 95928, 95929, 95938, and 95939 for Somatosensory Evoked Potentials/Responses (SEPs/SERs).
Use CPT codes 92651, 92652, and 92653 for Brainstem Auditory Evoked Potentials/Responses (BAEPs/BAERs).
Use CPT code 95930 for Visual Evoked Potentials/Responses (VEPs/VERs).

Neurophysiology Evoked Potentials (NEPs) — including Somatosensory Evoked Potentials (SEPs), Brainstem Auditory Evoked Potentials (BAEPs/BAERs), and Visual Evoked Potentials (VEPs/VERs) — are covered when determined to be reasonable and necessary in accordance with LCD L34975.
CT or MRI scans of the head or neck are covered when the medical record documents the scan is reasonable and necessary for diagnostic evaluation.
Coverage requires documentation supporting clinical indication such as history and physical exam findings, laboratory results, and signs or symptoms that justify the diagnostic test.
Perform SEPs/SERs in evaluation of myoclonus to assess somatosensory pathway involvement.
Perform SEPs/SERs in the assessment of comatose patients when testing of somatosensory pathways is indicated.
Use VEPs/VERs to detect optic neuritis at an early or subclinical stage.
